Compass Polyline Adjustment

This command applies a compass adjustment to a perimeter defined by a polyline. The command draws a new polyline of the adjusted perimeter and creates a report. The closure error is the difference between the end point of the polyline and the specified closing point that the program prompts for. For a closed loop adjustment, the closing point is the starting point of the polyline. Here is an example report for a closed loop.
